Reusability of the Cu/Ni-based colloidal catalysts stabilized by carboxylates of alkali-earth metals for the one-step amination of dodecyl alcohol and dimethylamine

Amination of isopropanol to isopropylamine over a highly basic and active Ni/LaAlSiO catalyst

“…For instance, it was reported that the addition of Mg into Ni for the formation of intermetallic Mg-Ni alloy benefitted the synthesis of polyethylene glycol amines from the amination of polyethylene glycol [21]. The addition of Cu into Ni was also found to increase the activity and stability of the amination reactions [22,23].…”

Catalytic Amination of Octanol for Synthesis of Trioctylamine and Catalyst Characterization

“…The amination mechanism of alcohols to mono-alkyl tertiary amines (RNMe 2 ) was reported elsewhere [6][7][8]15]. A simple amination mechanism for alcohols to tri-alkyl tertiary amines (R 3 N) was postulated in the article [2].…”

Gas phase amination of octan-1-ol over a cu-cr catalyst

“…In the case of the reductive amination of linear alcohols (e.g. octan-1-ol) the reaction scheme can be simplified as follows: The reaction between ammonia and octan-1-ol gives octylamine (1) which further reacts with octan-1-ol to dioctylamine (2). Similarly, the resultant dioctylamine reacts with the alcohol to trioctylamine (3).…”

“…The secondary and tertiary amines can also be a result of disproportionation (5 and 6). Dehydrogenation of the primary amine gives the corresponding nitrile (4 (1) (2) (3) (4) (5) (6) The chemistry of primary amine formation from an alcohol can be written as a group of consecutive reactions. In the first step the alcohol is dehydrogenated to an aldehyde (7) as proved by the experiments using octanol with deuterium [1].…”

“…In the open literature the catalysts used in this process are inaccessible. Active components of some catalysts usually contain metals such as: Ni, Cu, Cr, Co, Fe [2][3][4][5][6][7][8].…”
